A joke I made to generate a fake CSV listing of notes mapped to student names/scipers

NotesRandomizer.scala

import java.io.PrintWriter

import scala.io.Source
import scala.util.Random

/**

  */
object NotesRandomizer {
  val namesAndScipers: List[String] = Source.fromFile("names.csv").getLines().map(a => a.split(";")(0)).toList

  val notes: List[Double] = Source.fromFile("notes.csv").getLines().map(_.split(";")(2).toDouble).toList


  val shuffled: List[Double] = Random.shuffle(notes).map(v => {
    val change = Random.nextInt(11) - 5
    Math.abs(v + change)
  })

  val outArray: List[(String, Double)] = namesAndScipers zip shuffled

  val str: String = outArray map { case (name, note) => name + ";" + note } mkString "\n"

  def main(args: Array[String]): Unit = {
    println(str)

    new PrintWriter("output.csv") { write(str); close() }
  }

}
